Apologies if this was already asked or is a dumb question but I was wondering exactly how the different Shards function on a cosmic scale.
We know they are reflections of the Source. We also know that there's an actual universe in XIV, as demonstrated by the existence of Astrologian and Omega and Midgardsormr who traveled actual physical distances to reach the Source from other, inhabited worlds, no dimensional hopping tomfoolery involved.
But what if inhabitants of the shards were able to space travel? Could an inhabitant of the First meet with an inhabitant of the Second if they both traveled to the moon? Is the XIV cosmos shared between the Shards or did Hydaelyn make reflections of the entirety of the XIV universe, thirteen times over? I know Hydaelyn is a powerful entity but such a feat seems pretty farfetched.
